The FLIR DM66 TRMS Multimeter is a versatile and advanced handheld electronic testing device designed to provide accurate measurements for electrical parameters. The multimeter comes enclosed in a sturdy, compact box that ensures its protection during transportation and storage.
The DM66 multimeter is equipped with True RMS sensors, which enable it to provide true RMS values for voltage, current, resistance, and other electrical parameters. This feature makes it ideal for measuring AC and non-linear loads, ensuring reliable and accurate readings. The multimeter also features a backlit LCD display with a high resolution of 230 x 172 pixels, allowing for easy reading of test results even in low-light conditions.
The DM66 multimeter offers a wide range of measurement functions, including DC voltage, AC voltage, DC current, AC current, resistance, continuity, diode test, and capacitance. It also includes a min-max-average function that can record and display the minimum, maximum, and average values of a measured parameter. The multimeter has a measurement range of DC 200mV to 1000V, AC 400V, and a current range of 200mA.
The multimeter features a rotating, auto-ranging dial that makes it easy to select the desired measurement function and range. It also includes a data hold function that freezes the display reading to ensure that the value remains visible for a longer time. The multimeter has a high input impedance of 10M , making it suitable for measuring voltages without loading the circuit under test.
The DM66 multimeter comes with built-in safety features, including overvoltage protection, overcurrent protection, and overload protection. It also includes a low battery indicator that alerts the user when the battery needs to be replaced. The multimeter is RoHS compliant and has an operating temperature range of -20 C to 60 C.
The box that houses the DM66 multimeter is made of tough, impact-resistant materials that provide excellent protection against drops and impacts. It also includes a belt clip that allows the user to easily attach it to their belt or toolbox. The box includes a storage compartment for the test leads and a battery compartment for the included 9V alkaline battery. The box also includes a user manual and a pouch for the test leads. Overall, the FLIR DM66 TRMS Multimeter in its protective box is an essential tool for electrical technicians and electricians, offering precision, durability, and ease of use.
